European Oak Plywood

This product can be used in a variety of different ways and is suitable for many applications. It is
commonly requested for its hard-wearing surface layer veneer (e.g. for flooring applications), or due
to its high strength & rigidity (e.g. musical instruments). It is also regularly used in the manufacture
of decorative furniture, where the core is to be seen, or even accentuated, and the desire is to have
an edge with the uniform colour of European oak throughout the panel.

Winwood Products is a European oak plywood supplier offering the following configurations/options:

Oak throughout plywood:

European Oak throughout plywood is a very strong and stable alternative to lumber, panels
manufactured from edge-glued oak lumber strips, while offering
a face and core of rotary peeled European oak.

Plywood panels of this type are generally produced using minimum 1.66mm rotary peeled oak face veneers
on a core of 1.66mm & 2.5mm rotary peeled oak veneers, all of which are sourced from European forests.

Oak throughout plywood can be manufactured to your exact specification if required. For instance 2.5mm
face veneers, or a non-standard core layup e.g. using 2.5mm right throughout the core and face, could
be accomodated to suit your exact needs.

All these choices are available in the form of oak throughout plywood, or as 'oak combi plywood' or
'oak twin plywood' (see Oak Faced Plywood below).

Oak faced plywood:

Hard-wearing faces of minimum 1.66mm rotary peeled European oak veneer can be bonded onto a core made
up of alternating layers of oak and another specie (called 'combi plywood') or with just the faces in
oak and the core made entirely of another wood (called 'twin plywood').

Typically, oak combi plywood and oak twin plywood are based upon cores of ood are based upon cores of
silver fir plywood, beech plywood,
maple plywood or poplar plywood.
The reasons for choosing any particular arrangement may be manyfold, but such combinations are regularly
chosen to reduce the weight of the overall panel, to reduce the cost, or to offer a contrasting coloured
edge as a decorative feature.

Unidirectional oak plywood (oak drawerside plywood):

Unidirectional European oak plywood has a core that is arranged with all the veneers lying in one direction,
rather than the usual layup of each veneer being at right angles to the one above/below it.

This arrangement offers increased strength/stiffness in the direction of the grain, and more flexibility
in the other, allowing the panel to bend across the grain as the stiffness in this direction is reduced.
It is often used for aesthetic purposes, for instance if the edge of the panel is to be seen and end
grain of every other core veneer would be detrimental to the overall effect, or to avoid cross-grain
tearout where deep grooves are to be run into the surface.

Generally, the core veneer immediate beneath the face is bonded at right angles to all others, as this
has been found to offer increased stability across the face and therefore to reduce the incidence of
splitting on the face veneer due to the increased flexibility of the panel across the grain, although
the mill can lay all the veneers in the same direction if specifically instructed.

This type of product is regularly employed for applications such as oak drawerside plywood, oak skirtings,
decorative face carvings, and other similar uses.

Core quality:

Oak throughout plywood has core veneers that are 'closed', i.e. no open defects are allowed in the core,
while oak combi plywood & oak twin plywood is available with closed core veneers, or standard core
veneers (allowing some knotholes and open defects in the core, in a similar way to birch plywood).

The high face quality is maintained whether 'closed core' or 'standard core' construction is requested
- the choice only affects the core of the plywood itself.
